The state Department of Health and Human Services on Monday was scheduled to release its study of the industrial pollutant near a closed Alcoa Inc. aluminum smelter. State officials also scheduled a community meeting near the Stanly County site to discuss the study.

Environmentalists represented by Duke University law professor Ryke Longest collected data from the study under a public records request. Longest says the health agency's data shows the PCB contamination is broader than previously thought and officials have been slow to warn the public against eating fish.
